Try to not make your shapes too small or complicated as they won't stand out very well in your final shot.ĭuring the evening, the glow coming from various colourful lights in towns and cities make perfect backgrounds for this technique. You need to decide on a shape cut it out of the card then fast the card around your lens like you would a lens hood. You don't just have to settle for circular out of focus highlights as you can use black card and a pair of scissors to change the shapes that appear. If you don't have a subject in the foreground and are going for a more abstract shot you'll need to focus manually. Putting a little distance between your subject and the background will also help enhance the effect. Make sure you focus on your subject at the front of the frame too so everything behind can fall nicely out of focus. You may think that using the maximum aperture will give you the best results but sometimes it's worth using a slightly smaller aperture so you can still make out some of the shapes in the background of the shot. Longer lenses tend to produce better results too, however, some lenses will produce better bokeh in some situations than others so try putting your lens to the test, shooting close up portraits against a background that has highlights that can be thrown out of focus. Generally, the more expensive lenses have more blades and as a result, they generally create bokeh that's more pleasing. The more blades there are, the rounder the opening will be which can mean the shape of the out-of-focus highlights in the background of your shot (the bokeh) will be more circular. These blades are what open and close to let more/less light through onto the sensor. The shape of your lens aperture will change depending on how many blades are used and what shape they are. Different apertures and how far you are from your subject also affect how good the bokeh will look in your shot. Good bokeh will show attractive out of focus highlights and how the lens you're using is designed and the shape of its aperture play an important role in creating bokeh that works. Bokeh is the term used to describe how good the out of focus blur, which is usually in the background, looks.
